The Renaissance Center http://en.wikipedia.org/wiki/Renaissance_Center, is the world headquarters for General Motors, and the Detroit Marriott is the tallest all hotell skyscraper in the Western Hemisphere. I went to Detroit as part of my architectural photography tour and only had time to photograph the building with the sky that was presented to me. It is a lovely building nonetheless and I would like to go back and photograph it in more detail. See more big buildings and city skylines on our GigaPan gallery here and at http://kevingsaunders.com
